3. Drogo rapes Daenerys (Episode 1, "Winter Is Coming")

Women have it tough in the world of Game of Thrones, and none of the women we've met so far have it tougher than Daenerys. Used as a bargaining chip by her power-hungry older brother Viserys, Dany isn't so much the bride at her wedding to hulking warlord Drogo as she is one of his wedding presents. It's easy to forget by the end of the season, by which point Dany and Drogo's doomed relationship has bizarrely blossomed into a romance for the ages ("Moon of my life!" "My sun and stars!"), but their marriage begins in tears, and in one of the most difficult-to-watch scenes even sex-and-violence-soaked HBO has ever shown.
